• Creating blob properties with Entity Framework 4?

  - by David Veeneman

  I am creating an EF4 model-first application with a WPF UI. One of the controls on my UI is a RichTextDocument, which outputs a WPF FlowDocument. I can either serialize the FlowDocument to a byte array, or extract its XAML markup as a string. I would prefer to use binary serialization, if I can. Here are my questions: If I serialize to a byte array, how do I specify an entity property as a byte array in the EDM Designer? If I extract a XAML markup string, can I specify that the EDM Designer create the corresponding database column as a nvarchar(max) column? As to the second question, I assume I could always manually edit the MyModel.edmx.sql file to change the data type from nvarchar(4000) to nvarchar(max) before executing it, but I would like to know if it can be done in the Designer. Thanks for your help.

• RouteTable.Routes.GetVirtualPath with route data asp.net MVC 2

  - by Bill

  Dear all, I'm trying to get a URL from my routes table. Here is the method. private static void RedirectToRoute(ActionExecutingContext context, string param) { var actionName = context.ActionDescriptor.ActionName; var controllerName = context.ActionDescriptor.ControllerDescriptor.ControllerName; var rc = new RequestContext(context.HttpContext, context.RouteData); string url = RouteTable.Routes.GetVirtualPath(rc, new RouteValueDictionary(new { actionName = actionName, controller = controllerName, parameter = param })).VirtualPath; context.HttpContext.Response.Redirect(url, true); } I'm trying to map it to. However RouteTable.Routes.GetVirtualPath(rc, new RouteValueDictionary(new { actionName = actionName, controller = controllerName, parameter = param })) keeps giving me null. Any thoughts? routes.MapRoute( "default3", // Route name "{parameter}/{controller}/{action}", // URL with parameters new { parameter= "parameterValue", controller = "Home", action = "Index" } ); I know I can use redirectToAction and other methods, but I would like to change the URL in the browser with new routedata.

• WPF, PreviewKeyDown event and underscore char

  - by commanderz

  Hi, I'm catching key hits with PreviewKeyDown event in my WPF component. I need to distinguish characters being typed: letters vs. numbers vs. underscore vs. anything else. Letters and numbers work fine (just convert the Key property of the KeyEventArgs object to string and work with character 0 of that string), but this won't work for underscore. It's ToString value depends on localized keyboard settings (it shows up as "OemMinus" on EN/US keyboard and "OemQuestion" on CZ/QWERTY keyboard). So how can I RELIABLY find out, if the typed char is underscore in the PreviewKeyDown event? Thanks for any help

• WPF DataGrid AutoColumn generation via ICustomTypeDescriptor.

  - by panamack

  In a test project I've managed to AutoGenerate WPF DataGrid columns in the following scenario, where the data is stored in a Dictionary and binding is performed via PropertyDescriptors: public class People:List<Person>{ ... } public class Person:Dictionary<string,string>,INotifyPropertyChanged,ICustomTypeDescriptor { } The problem I'm having is in my real life project I'm using MVVM so it's *People*ViewModel which inherits ViewModelBase and hence can't inherit List<Person>. I've tried implementing IList<Person> instead with an internal List<Person> and explicitly setting the DataContext to an IList<Person> reference but that didn't work. I've seen a similar post on binding a win forms DataGridView here, so I'm wondering if the same sort of logic applies in WPF and primarily, what exactly causes the ICustomTypeDescriptor implementation to be picked up when inheriting List<T> that is missing when you simply implement IList<T> instead.

• Active Directory Services: PrincipalContext -- What is the DN of a "container" object?

  - by Ranger Pretzel

  I'm currently trying to authenticate via Active Directory Services using the PrincipalContext class. I would like to have my application authenticate to the Domain using Sealed and SSL contexts. In order to do this, I have to use the following constructor of PrincipalContext (link to MSDN page): public PrincipalContext( ContextType contextType, string name, string container, ContextOptions options ) Specifically, I'm using the constructor as so: PrincipalContext domainContext = new PrincipalContext( ContextType.Domain, domain, container, ContextOptions.Sealing | ContextOptions.SecureSocketLayer); MSDN says about "container": The container on the store to use as the root of the context. All queries are performed under this root, and all inserts are performed into this container. For Domain and ApplicationDirectory context types, this parameter is the distinguished name (DN) of a container object. What is the DN of a container object? How do I find out what my container object is? Can I query the Active Directory (or LDAP) server for this?

• Why model => model.Reason_ID turns to model =>Convert(model.Reason_ID)

  - by er-v

  I have my own html helper extension, wich I use this way <%=Html.LocalizableLabelFor(model => model.Reason_ID, Register.PurchaseReason) %> which declared like this. public static MvcHtmlString LocalizableLabelFor<T>(this HtmlHelper<T> helper, Expression<Func<T, object>> expr, string captionValue) where T : class { return helper.LocalizableLabelFor(ExpressionHelper.GetExpressionText(expr), captionValue); } but when I open it in debugger expr.Body.ToString() will show me Convert(model.Reason_ID). But should model.Reason_ID. That's a big problem, becouse ExpressionHelper.GetExpressionText(expr) returns empty string. What a strange magic is that? How can I get rid of it?

• Visual Studio 2010 error: Type universe cannot resolve assembly

  - by dthrasher

  I've loaded a WPF project initially created in Visual Studio 2008 into Visual Studio 2010. The conversion process goes smoothly, but on certain XAML files the VS2010 designer throws several errors related to project references, including this one: System.Reflection.Adds.UnresolvedAssemblyException Type universe cannot resolve assembly: GalaSoft.MvvmLight, Version=3.0.0.31869, Culture=neutral, PublicKeyToken=3e875cdb3903c512. This assembly reference works just fine in the Expression Blend 4 designer, but not in VS2010. I can build and run the solution successfully. My solution targets the .Net Framework 3.5 SP1.

• Reflect on an ExpandoObject

  - by Water Cooler v2

  I have written a nifty function that will accept a system.object, reflect on its properties and serialize the object into a JSON string. It looks like this: public class JSONSerializer { public string Serialize(object obj) Now, I want to be able to do this to serialize a dynamic/ExpandoObject, but because my serializer uses reflection, it isn't able to do it. What's the workaround? public class Test { public dynamic MakeDynamicCat() { dynamic newCat = new ExpandoObject(); newCat.Name = "Polly"; newCat.Pedigree = new ExpandoObject(); newCat.Pedigree.Breed = "Whatever"; return newCat; } public void SerializeCat() { new JSONSerializer().Serialize(MakeDynamicCat()); } }

• iTextSharp renders image with poor quality in PDF

  - by Sebastian

  Hello, I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it. First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly. The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference. My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation. The code to render the image is the following: Dim para As Paragraph = New Paragraph para.Alignment = Image.RIGHT_ALIGN para.Add(text) Dim imageFile As String = String.Format("{0}{1}", GetAppSetting("UploadDirectory"), myCompany.LogoUrl) Dim thisImage As Image = Image.GetInstance(imageFile) thisImage.Alignment = Image.LEFT_ALIGN para.Add(thisImage) The printed images are the following: Image printed directly with iTextSharp Image edited and printed with Acrobat 8 Please let me know if I need to provide more info. Thanks
